Any mounting of the product should follow the manufacturer’s instructions, and should use a mounting accessory recommended by the manufacturer. A product and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the product and cart combination to overturn. Ventilation – Slots and openings in the cabinet are provided for ventilation and to ensure reliable operation of the product and to protect it from overheating, and these openings must not be blocked or covered. The openings should never be blocked by placing the product on a bed, sofa, rug, or other similar surface. This product should not be placed in a built-in installation such as a bookcase or rack unless proper ventilation is provided or the manufacturer’s instructions have been adhered to. Power Sources – This product should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, consult your product dealer or local power company. For products intended to operate from battery power, or other sources, refer to the operating instructions. Grounding or Polarization – This product may be equipped with a polarized alternating current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug. Power-Cord Protection – Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the product. 2 3 4 5 6 7 8 9 10 11 12 13 i 14 15 16 17 18 19 20 21 22 23 Lightning – For added protection for this product during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the product due to lightning and power-line surges. Power Lines – An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.

Refer all servicing to your Yamaha dealer. • Never open the cabinet. If a foreign object drops into the set, contact your dealer, and do not use the YST-MS50s. Otherwise, you may cause a fire. • Do not expose the YST-MS50s to temperature extremes, direct sunlight, excessive dust, humidity, or vibration. • Position the YST-MS50s on a level, stable surface. Do not drop the YST-MS50s, apply excessive force to their controls, or put heavy items on top of them. • Since this unit has a built-in power amplifier, heat will radiate from the rear panel. Therefore, place the unit away from walls, allowing a space of at least 20 cm (7.9") above, and 10 cm (4") behind and at the sides. Also, do not position with the rear panel facing down on the floor or other surface. (Subwoofer only) • Do not obstruct the port with your hand or a foreign object. • To protect the YST-MS50 speakers, avoid microphone feedback, continuous and excessive output from electronic musical instruments, and excessive signal distortion. • If the YST-MS50s are located close to fluorescent or neon lights, a slight hum may be heard. In this case, relocate the YST-MS50s away from the light. • Although the YST-MS50 speakers are magnetically shielded, keep floppy disks and tapes away from them. • The YST-MS50s may cause picture distortion when located close to a television or computer monitor. In this case, move them away a short distance. • Avoid sources of hum (transformers, motors). To prevent fire or electrical shock, do not expose to rain and water. • Do not use force on switches, knobs, or cables. When you move the YST-MS50, first turn off the power to the speakers, then disconnect the power cable from the AC outlet and the cables from the connected devices. • Always turn the volume control counterclockwise to the minimum before starting to play the audio source: increase the volume gradually to an appropriate level after the playback has started. • Do not turn off the POWER switch on the subwoofer while the (standby/on) button on the front panel of the right satellite speaker is on (while the standby/on indicator is lit). Otherwise, the speakers may be damaged. Note for headphone: When you use headphones, make sure that they have a cable of less than 3m. (UK and Europe models) Connections & Controls Refer to the illustrations on page 1. 1 BASS control: Use this control to adjust the volume of the subwoofer. We recommend that the control be set to the 12 or 1-o’clock position. Turn it clockwise to increase the volume; counterclockwise to decrease it. 2 Main POWER switch: Normally, leave this switch in the ON position. When you will not use this unit for a long period of time, set this switch to the OFF position. 3 TO RIGHT SPEAKER: Using the 8 pin plug cable, connect this jack to the TO SUB Wo. jack on the satellite right speaker. 4 TO LEFT SPEAKER: Using the RCA pin plug cable, connect this jack to the TO SUB Wo. jack on the satellite left speaker. 5 6 7 8 9 0 (standby/on) button and indicator: Press the (standby/on) button to turn on the YST-MS50s; the standby/on indicator lights up. Press again to turn off. Turn down the VOLUME control before turning on and off the YST-MS50s. A small amount of power is always consumed even while the YST-MS50s are on standby. (Headphone): A pair of stereo headphones can be connected here for private listening. The YSTMS50 speakers do not produce sound when headphones are connected to this jack. VOLUME control: Use this control to adjust the volume of the left and right speakers. Turn it clockwise to increase the volume; counterclockwise to decrease it. INPUT 1 and 2: These 3.5 mm stereo mini jacks are used to input signals independently to the YSTMS50. You can, for example, connect a CD player and personal computer to these jacks. The signals from these jacks are mixed together. TO SUB Wo. (on the right): Using the 8 pin plug cable, connect this jack to the TO RIGHT SPEAKER on the subwoofer. TO SUB Wo. (on the left): Using the RCA pin plug cable, connect this jack to the TO LEFT SPEAKER jack on the subwoofer. 2 English Thank you for purchasing Yamaha’s YST-MS50 Powered Multimedia Speakers. Advanced Yamaha Active Servo Technology offers exceptionally high performance, allowing these compact speakers to produce a rich bass sound.  Non skid pad To prevent the speakers from sliding around, attach the supplied pads to the four points on the bottom of each satellite speaker. Place the speaker on a stable, flat surface. Specifications Type ..........................
